Improved podophyllotoxin production by transformed cultures of Linum album.
Various cell and hairy root cultures of L. album were developed and analyzed for podophyllotoxin content. Transformed callus and hairy root cultures developed from infection of stem portions of in vitro-germinated L. album plant with Agrobacterium rhizogenes NCIM 5140 strain were selected on the basis of high podophyllotoxin content and growth. Based on the integration of Ri T(L)-DNA and T(R)-DNA, integration of only the ags and not the rol gene in transformed cell culture indicated fragmented integration pattern. The effect of different cultivation media and carbon source on growth and podophyllotoxin production were studied in shake-flask suspension cultures. Detailed batch growth and production kinetics with sugar consumption profile were also established. Maximum volumetric productivity of 4.40 and 2.75 mg/L per day was obtained in cell suspension and hairy root cultures, respectively.
